An adjustable rehabilitation and exercise device, including a rotary member rotatable about a hub and having an elongated slot defined thereon extending radially relative to the hub, the slot including a plurality of spaced apart and opposed fingers along the length of the slots, with a plurality of gaps defined between the fingers of each side of the slot; and a mount selectively and movably positionable on a selected location on the slot of the rotary member to select an angular location of the mount. The mount includes a sliding member movably positionable along the slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The sliding member is configured to slidingly engage the slot, the slide member having at least one spring loaded lock configured to engage one of the gaps to lock the position of the sliding member, and a key operable by a user to disengage the lock from the gap to enable the sliding member to be moved to another location along the slot. A patient engagement member is connectable to the mount and movable with the mount.

An exercise apparatus comprising: a foot support, a user interface that includes a visual display, the foot support being movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to a selection device that enables the user to select any one of the plurality of arc segments, one or more detectors adapted to detect one or more of force, energy or power exerted by the user over time on the foot support or distance or velocity of travel of the foot support or resistance assembly during the course of the user's performance of all or a portion of an exercise cycle, the visual display displaying a visually recognizable format of one or more of the force, energy, power, distance, time or velocity.

An exercise apparatus includes a frame adapted to be rested on a floor surface, a crank mechanism that has two cranks mounted on the frame, two swing members pivotally mounted on the frame, two connecting assemblies, and a guiding device. Each of the two connecting assemblies has a plurality of connecting rods connecting the respective crank and the respective swing member. The two connecting assemblies define two pedal portions for supporting a user's feet, and up-and-down movement of the pedal portions causes rotation of the two cranks along a circular path. The guiding device is configured to connect the two swing members for guiding swing movement of the two swing members within a predetermined swing range. The predetermined swing range is adjustable so as to provide various exercise paths.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A dynamic belt-tensioning apparatus for a treadmill includes a base having a first end and a second end spaced from the first end. A foot-striking platform is movably supported by the base so as to allow vertical movement of the platform during operation of the treadmill. A drive belt has a fixed circumference and is positioned above a top portion of the platform. A drive roller is pivotally mounted adjacent to the first end of the base and engages the drive belt. A tensioning roller is pivotally mounted to the base and is capable of a range of movement to provide substantially constant tension to the drive belt in response vertical movement of the platform.

An exercise device with a pair of upper links coupled to the frame and a pair of lower links pivotally coupled to the upper links is provided. A pair of pedals is received on a distal end of each of the lower links. A transfer system between the pair of upper links may include a first and a second pushrod, each with a first end pivotally coupled to each upper link and a second end opposite to the first end. A first and a second pivot arm, each pivotally coupled to the frame, may be included, each pivot arm receiving a respective pushrod. A pliable connector may be coupled to the first pivot arm and the second pivot arm, thus providing compliant reciprocating movement of the upper links.

An exercise apparatus comprising a foot support movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to an arc segment selection device that is manually actuatable to enable the user to manually select any one of the plurality of different arc segments, the foot support being interconnected to an arm having a handle manually graspable by the user to reduce or increase power or energy required by the user to move the foot support.

The present disclosure discloses an exercise bicycle with a desk plate, comprising an exercise bicycle body assembly and a desk plate assembly, wherein the desk plate assembly comprises a desk plate and a fixing seat for the desk plate, the desk plate is in slide connection with the fixing seat for the desk plate, the fixing seat for the desk plate is connected with the exercise bicycle body assembly through a lifting assembly, the fixing seat for the desk plate can be lifted up and down relatively to the exercise bicycle body assembly due to the connection of the lifting assembly.

The present disclosure discloses an exercise bicycle with a desk plate, which comprises a frame, a supporting foot, a seat and a desk plate, the frame including a first upright column to support the desk plate and a second upright column to support the seat, wherein a first lifting assembly is provided on the first upright column to connect the desk plate and the first upright column, and enables the adjustment of the upper and lower positions of the desk plate relative to the first upright column. The height of the desk plate can be adjusted by the first lifting assembly to accommodate users with different figures. It's more ergonomic since the height of the upright column supporting the desk plate can be adjusted. When packing, lower the upright column to the minimum can largely reduce the size of the package.

A stationary exercise machine may include reciprocating hand members, such as handles, and/or reciprocating foot members, such as foot pedals. The reciprocating hand members may be operative to apply a first moment to a crankshaft, and the reciprocating foot members may be operative to apply a second moment to the crankshaft. The second moment may be different than the first moment. The reciprocating foot members may cause a user's feet to move along a closed loop path that is substantially inclined, such that the user's foot motion simulates a climbing motion more than a flat walking or running motion. The reciprocating hand members may be configured to move in coordination with the foot members via a linkage operatively coupling the hand members with the foot members. A resistance mechanism may apply resistance to crankshaft rotation, and the resistance mechanism may be adjustable while the user is using the machine.
